   • 1967, “Song about Bears”, in Кавка́зская пле́нница [Kidnapping, Caucasian Style]‎ (film):

     Где́-то на бе́лом све́те, / Та́м, где всегда́ моро́з, / Тру́тся спино́й медве́ди / О земну́ю о́сь. / Ми́мо плыву́т столе́тья, / Спя́т подо льдо́м моря́, / Тру́тся об о́сь медве́ди, / Ве́ртится земля́.

     Gdé-to na bélom svéte, / Tám, gde vsegdá moróz, / Trútsja spinój medvédi / O zemnúju ósʹ. / Mímo plyvút stolétʹja, / Spját podo lʹdóm morjá, / Trútsja ob ósʹ medvédi, / Vértitsja zemljá.

     Somewhere in the world, / Where it is always cold, / Bears are rubbing their backs, / Against the earth's axis. / The centuries are swimming by, / The seas are sleeping under the ice, / Bears are rubbing against the axis, / The earth is spinning.
